Kajusbagdonas Posted November 11, 2023 Share Posted November 11, 2023 My xtm xt2 buggy has the xtm 247 and has 2.6hp I was wandering if there are any engines I could upgrade to that have more power, I was looking on ebay and a lrp z. 28r caught my attention but I don't know if I should put it in my buggy.

wolfie1 Posted November 11, 2023 Share Posted November 11, 2023 For a cheap engine i quite like the force 36. You can increase the teeth on the clutch bell for more speed as its got more torque, i did have an lrp30 in a savage and it was more powerful than the force 36 but its more expensive Quote Link to comment Share on other sites More sharing options...
Yorkshireman Posted November 11, 2023 Share Posted November 11, 2023 As above...force engine's are pretty good for a reasonable price 👍 Just make sure you run it in properly first 😉 Quote Link to comment Share on other sites More sharing options...
locky Posted November 11, 2023 Share Posted November 11, 2023 You dont need too much power in a 1/8 buggy as it is relatively light in weight. A decent budget 21 engine such as a Fastrax Enduro 21 will be fast and driveable. But it all depends on where you bash and what you like. More hp the quicker the fuel tanks empties. 21 engines are usually higher revving whereas 28 engines have more low end torque. A buggy isnt really capable of using the extra low down torque, mainly due to tyre size. Quote Link to comment Share on other sites More sharing options...
Kajusbagdonas Posted November 11, 2023 Author Share Posted November 11, 2023 The force looks good but I have a tight budget around £80 and I can only see new force engines which are cheap, but the lrp I've seen costs £80 used, I've seen some cheap mac 28s which I believe that they are from the hyper but I haven't had any experience with them.

locky Posted November 11, 2023 Share Posted November 11, 2023 Buying used is a lottery as have past experience. Usually more cost effective to buy new as replacing piston/sleeve is a lot. Lowest price for Force 28 is probably this, I bougjt one last year and broke it this year with a conrod failure. Dont know why it failed as usually careful with breaking in. I also purchased a new Fastrax Enduro for £60 from Facebook marketplace this year so always worth a look. It is faster than the Force 28 in a buggy.

wolfie1 Posted November 11, 2023 Share Posted November 11, 2023 I wouldnt buy used on a nitro engine, you are probably just buying someone elses problems Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted November 11, 2023 Share Posted November 11, 2023 The XTM motor was a rebranded Force .25 A Force .28 will give you a little bit more grunt for not too much cash Quote Link to comment Share on other sites More sharing options...
Kajusbagdonas Posted November 12, 2023 Author Share Posted November 12, 2023 It will add a bit of power but I saw one used £80 and the seller told me he only used the engine for 2 runs. Quote Link to comment Share on other sites More sharing options...
